Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

This isn't even true. A Pi sells for 50$ yes, + USB cable for power + USB power adapter + case + whatever else money grab.
A second hand HP mini with an i5 7th gen CPU that is WAY faster comes with everything including 8 GB of RAM and 256GB of SSD (or better if you get a good deal) for around 80$. Tell me about your math again...
How's the power consumption compare between two performance equivalent setups? (Genuine question, it's something I'm trying to determine for my self-host use-cases).
My first RPi is for Joplin to replace OneNote. My current server runs 24/7 and costs about $1/day for power (it provides other services too). I haven't calculated my Pi power consumption yet, but it's running on a 2.5 watt power supply, vs my server 700 watt (of course, these are both peak measurements).
Given my self-host stuff will spend 99% of its time at idle, it seems like Pi has a massive advantage. But of course that all depends on how things are used and setup.
The raspberry pi, like all RISC chips, uses much less power.
In fact the super computer summit runs on powerpc64 which is a RISC chip, that's a big reason why its power consumption for a super computer is so low.
I hadn't considered the RISC angle. Does RISC consistently use less power than CISC at given operations levels (MFLOPS, for example), or is there another/better way to make a power-consumption vs operations/performance comparison?
I realize this is kind of esoteric for my use-cases, but it would be useful for making projections to see if spending X dollars on Y number of Pi's recoups the investment over a given period, just in power consumption.
E.G. If I can reduce my power consumption by 70% by switching to 3 Rpis, then I can recoup their cost in 2-3 years. Since my server needs replacing anyway, this seems like a no-brainer.
Yeah, a second hand old as shit hp, that'll die on you so quick. There's a reason that hp is selling for so cheap. HP is garbage, unless you're buying their actual servers...
Edit: also all the "cash grab" parts.. you probably already have those parts just lying around doing nothing.
Not my experience. At all.
Yes I sure have a proprietary adapter for their PCIe connector and a Pi case lying around. Just the case its about 30€ and suddenly it becomes as expensive as a second hand mini PC for 1/10 of the performance and reliability. See the problem now? Even with the power adapter, the RPI is picky and will require a decent thing that is usually more than your average smartphone.
This is self hosting... You're telling me you or one of your friends don't have a printer to print a case for less than a dollar? Shit, pay for shipping and I'll send you a case.
That's not my experience at all. I mean the other user already posted a PC you can buy for the same price as a pi. It's about as good as a 4, the 5 is 3x that speed.
See the problem now?
A metal chassis from an HP Mini will be always better than something 3d printed...
That other guy could've done better.
